Week 26 — MEV & Reading the Tape

How bots front-run you, and how to read candlesticks to see what's really happening.

Week 26 of 52 · ~7 hours · 13 slides · exam + project

Front-Running & Price Action

Understand the hidden tax on your trades — and learn to read the chart.

What you will learn

  • Understand MEV and front-running
  • Read candlesticks and patterns
  • Connect the two: why fair ordering matters

What MEV is

MEV (Maximal Extractable Value) is profit bots extract by seeing your transaction before it settles and acting first — front-running your trade, sandwiching it, or racing ahead of you. In transparent mempools, your order is visible to every bot before it lands.

💡 The sandwich attack

You submit a big buy. A bot sees it, buys first (pushing the price up), lets your order fill at the higher price, then sells back (pushing it down). You paid more; the bot pocketed the difference. This 'sandwich' is a hidden tax on naive trades.

AEON's answer: fair ordering

AEON's entropy-seeded ordering (Patent #5) removes the predictable first-come-first-served queue that bots exploit. Orders are sequenced using a cryptographic, unpredictable seed — so bots can't reliably front-run. It's a structural fix, not a speed race.

Reading a candlestick

A candlestick shows open, high, low, and close for a period. A green candle closed higher than it opened; a red candle closed lower. The body is open-close; the wicks show the high-low extremes. Candles compress a whole session of battle into one shape.

💡 What a long wick means

A long upper wick means price was pushed high but rejected — sellers overwhelmed buyers. A long lower wick means buyers stepped in at the lows. Wicks reveal rejection; bodies reveal conviction. Read them together to see who's in control.

Patterns are probability, not prophecy

Dojis, hammers, engulfing candles — these patterns describe recurring crowd psychology, but they're probabilistic, not predictive. They work best in combination with volume, context, and risk management, never as a standalone signal.

❓ Quick check

A sandwich attack makes the victim:

A) Pay less
B) Pay more (bot front-runs both sides)
C) Nothing
D) Earn fees

Key takeaways

  • MEV = bots extracting value from your visible orders
  • Candles show open/high/low/close; wicks = rejection, bodies = conviction
  • AEON's fair ordering is a structural defense against front-running

10 questions. Review the Deep Dive and courses before attempting.

1. MEV stands for:
Maximal Extractable Value.
2. Front-running happens because:

Buys before, sells after.
4. AEON's fair-ordering defense uses:
Unpredictable sequencing.
5. A green candle means:
Closed higher than it opened.
6. A long upper wick suggests:
Rejection at the highs.
7. Candlestick patterns are best described as:
Probabilistic, not prophetic.
8. The 'body' of a candle is:
